atent'ed Dec. 16,-- 191? T all whom it may concern:

'Be it known that I. JAMrJs-RJCRAVATH; citizen of the United States, residing at Chicago, in the county of Cook and\State of Illinois, have invented certain new\anduseful Improvements in Lanterns; and I d0 hereby declare the following to be a ful. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and usethe same.

My invention relates to lighting fixtures and more particularly to the type of appli ances known as lanterns and used for shielding outdoor lighting units and for distributlng the light thereof. In lighting appliances of this class ithas been customary in some cases heretofore t0 providea reflector v over the lamp both for protecting the lamp g0 and for reflecting in useful downward directions the rays of light which would otherwise be wasted in upward directions. It has also been customary in other cases to provide an inclosing globe or bowl disposed below a hood for the purpose of protecting the lamp from the weather and from accidental breakage and for affording an ornamental diifusing inclosure for the lamp. A third method has been to combine a reflector no with an inclosing globe by attaching the globe to the reflector, in whichcase the metal 'ring or other device securing the globe to the reflector obstructed and wasted considerable light. ther by greatly reducing the as effective surface 0 the reflector. It has not heretofore been feasible to provide bothan effective reflecting surface abovethe lamp and an inclosing globe around the lamp without either making the reflector unduly to large and, cumbersome or wastin considerable light and losing the elfect of a considerable portion of the reflector surface be cause of the obstruction offered by the band or collar holding the globe below the re-; 4L5 Hector. This is because the reflecting surfacecOuld not closely approach the neck of thelamp bulb butterminated outside of the from the lamp itself.

One ob'ect of In" invent' n is to provlde a lighting applian combin ng'a translucent protecting inclosure or globe for the lamp with a reflector extending both inwardly and-outwardly of'the juncture of the globe with the reflector, so as also to utilize the redoctor for redistributing rays which have larlydisposed m mber or' members engagequipped with a threaded inlet 2 e 1? p p eg from t h d 1? and}? heretofore been used very ineh'icie'ntly owing to their being within the .upward angles in closed by the inner edge. of the "reflector and the globe holder. 4 Other objects'are to provide simple means for supporting-the. globe by clamping-the same between-the refiectoragainst which the upper end of the globe abi ts and an annu '65 mg the lower end of the'globe;ftoprovide means for supporting. the said. member or me hers independently of the reflectonIand for readily detaching theformer to permit access\to the interior of the globe or to permit th e replacing of the latter; and to provide a' sgmple lighting. appliance pre'sentin the clasc'c'appearance of an ol'd 'fashione lantern, but permitting the ,efii'cientluse of a modern illu iinant. such. as electricity or gas.

- I accor'np ish these objects by. a construction .shown tin the accompanying drawings" in which: 1

c Figure l is, a sectional View of an electric lighting appliance embodying my invention. Fig.- '-.2 is a fra mentary bottom View of lt-he appliance o f Fig. -1-.' Figs. and--1- show alternative arrangements of the supporting members'of my appliance. Fig. 5- is a fragmentary sectional viewshowing a modified-arrange ment of the re i ector and the portion of the inclosure abutt g against the-same.

Inthe embod'ment of Fig. '--1'- theappliance of my in elation has a hood iortion 1 y' whichv it. is attached to "bracket pipe 3, the bore of the said pipe per iitting wires .to bebrought through the sam into the interior of the so preferablyatsomdistance above the-lowerff-l. edge or mouth th re'of' are a plurality oflugs 4 to which cli s 5 are secured by screws 6, the said/clips 5 supporting the projecting edge portion of a s cket 7 for-an incandes- I00 centlanip' 8 depend ng rertichlly from the said sockehPositioi 'ed horizontally across v 'th e' mouthof the ho d l is an annular re inclosing globe, or at a considerable distance flecto'r 9 of enameled steel or other sfu'itable material having a reflectin .surfaceupon its lower face and harih a"c-entralperf0ra'- the largest diameter-{of I reflector 9 intermediate of the periphery of 1-, it willbe evident from the lines l4 the latter and the annularperforation therein; The inclosure 11 is supported by an annular member 12 having an inwardly projecting lip portion contracted to a smaller diameter than the said inclosure, the said annular member being supported by bolts 13 threaded into the-lugs 4c.

When the parts are assembled as in Fig.

, representing light rays that'the reflector 9 will direct the rays of the lamp striking the portion of the reflector radially'just outside of the inclosure 11 which in previous forms would have been obstructed by the globe holder ring; also that the rays 15 reaching the portion of the reflector within the said inclosure will likewise be redirected by the reflector. Consequently, the efliective area of the reflector will be considerably increased without increasing the diameter thereof. It will also be evident that by unscrewing the bolts 13 the inclosure 11 can readily be removed, replaced or cleaned upon its interior, and that the upright bolts 13 in combination with the annular member 12 extending around the lower edge of the translucent inclosure will produce an appearance imitating the classic design of the old-fashioned oil lanterns as used upon building fronts in Europe during previous centuries, so that the fixture of my invention will combine the classic appearance of the old-fashioned lantern with an eflicient use of the modern illuminant Moreover, the inclosure 11, which may be either of clear or opalescent glass will simultaneously protect the lamp against deposits of dust and against mechanical strains for .which the frail lamp bulb would not have adequate strength.

' While I have shown the inclosure 11 as 7 having a closed bottom and as supported by an annular member secured to the hood by detachable bolts, I do not wish to be limited to this or other details of the construction herein disclosed, it being evident that the same might be varied in many ways without departing from the spirit of my invention. Forexample, Fig. -3 shows an alternati've arrangement in which the glass inclosure is open at the bottom so as to permit the entrance of a handfor removing the lamp or cleaning the interior of the inclosure, while Fig. 4[ shows a construction in which the member fengaging the lower edge of the glass inc losur e is supported from the reflector 1tself, and Fig -5 shows an alternative arrangement having a cushioning member 16 interposed between the abutting portions of the reflector and the inclosure to prevent the entrance of dust at the said juncture.

n will be evident that none of the embodiments which I show have any screw ring, band, or similar fastening member interposed at the juncture of the glass inclosure and the reflector, hence I avoid the wasting of reflecting surface by the width of the fastening member and the shadows cast thereby, being able to use a reflector reaching substantially up to the neck of the lamp bulb and unobstructed over its whole diameter. I claim as my invention:

1. A lighting appliance including a lamp,

said open end against thereflector, the said.

reflector extending both inwardly and outwardly of the said abutting end of the inclosure, and a plurality of supports for the other end of the inclosure, the said supports coacting to support the inclosure independently of the reflector.

3. A lighting appliance including a lamp, a support therefor, a reflector, a translucent inclosure for the lamp abutting at one end against the reflector, the said reflector extending both inwardly and outwardly of the said abutting end of the said inclosure, an annular memberengaging the other end of the inclosure, and a plurality of auxiliary members connecting the annular member with the said support, the said auxiliary members 'coacting with the annular member to support the inclosure and being adjustablev to permit the distance between the annular member and the support to be varied to move the inclosure into and out of its said abutting engagement with the reflector.

4. A lighting appliance including a hood, a lamp supported thereby and depending vertically therefrom, a horizontally dis osed perforated reflector carried by the hoo the neck of the said lamp projecting through a perforation in the said reflector, a translucent inclosurefor the lamp abutting at its upper end against the said reflector intermediate of the periphery of the latter and the said perforation therein, and means carried by the hood for supporting the said inclosure in its said abutting engagement with they reflector.

. 5. A lightin appliance including a lamp,

' theneck ortion of the said lam projecting through t e said perforation an being ad acent to the edge thereof a substantially cylindrical inclosure for the lamp abutting at its upper end against the reflector intermediate ofthe said erforation and of the periphery of the re ector, and supporting means carried by the hood for supporting the said inclosure in its said abutting engagement with the reflector, the said sup porting means being adjustable to permit the inclosure to be moved into and out of its said abutting engagement with the reflector.

6. A lighting appliance including a socket, a lamp-carried thereby and depending vertically therefrom, a support for the socket equipped with a substantially horizontal reflector, the said reflector having a perforation therein larger than the neck portion of the lamp but of smaller diameter than the largest portion of the bulb of the lamp, the neck portion of the said lamp eX- tending through the said perforation in the reflector, a substantially cylindrical translucent inclosure for the lamp open at its upper end and abutting at its said end against the said reflector intermediate ofthe periphery of the latter and the perforation therein, and supporting members carried by the said support and supporting the said inclosure in its said abutting engagement with the reflector.

In testimony whereof I have signed my name in presence of two subscribing Witnesses. 7
